Hi!

So first subtract 9 to both sides

8n = -n - 9

Now you want the n on one side and the constant on the other

so add the single n to the n side

9n = -9

Divide 9 to both sides to solve for n

n = -1

Hope this helps!

8n+9=-n\ \ \ \ \ |+n\\\\9n+9=0\ \ \ \ |-9\\\\9n=-9\ \ \ \ |:9\\\\\boxed{n=-1}
